Polyhydroxyalkanoates: the natural biopolyester for future medical innovations.

Polyhydroxyalkanoates (PHAs) are a family of natural microbial biopolyesters with the same basic chemical structure and diverse side chain groups. Based on their excellent biodegradability, biocompatibility, thermoplastic properties and diversity, PHAs are highly promising medical biomaterials and elements of medical devices for applications in tissue engineering and drug delivery. However, due to the high cost of biotechnological production, most PHAs have yet to be applied in the clinic and have only been studied at laboratory scale.

Affinity of Streptococcal G Protein to Forest Musk Deer () Serum Immunoglobulin G.

Forest musk deer (FMD; ) immunoglobulin G efficiently bound to streptococcal G protein (SPG) and weakly bound to staphylococcal A protein. The results suggested that horseradish peroxidase-conjugated SPG could be chosen as an enzyme-labeled antibody substitute and laid a foundation for immunologic research in FMD disease.

Design, synthesis and biological evaluation of N-phenylquinazolin-4-amine hybrids as dual inhibitors of VEGFR-2 and HDAC.

A single agent that simultaneously inhibits multiple targets may offer greater therapeutic benefits in cancer than single-acting agents through interference with multiple pathways and potential synergistic action. In this work, a series of hybrids bearing N-phenylquinazolin-4-amine and hydroxamic acid moieties were designed and identified as dual VEGFR-2/HDAC inhibitors. Compound 6fd exhibited the most potent inhibitory activity against HDAC with IC50 of 2.

Hybrids from 4-anilinoquinazoline and hydroxamic acid as dual inhibitors of vascular endothelial growth factor receptor-2 and histone deacetylase.

A series of hybrids derived from 4-anilinoquinazoline and hydroxamic acid were designed, synthesized, and evaluated as dual inhibitors of vascular endothelia growth factor receptor-2 (VEGFR-2) tyrosine kinase and histone deacetylase (HDAC). Most of these compounds exhibited potent HDAC inhibition and moderate VEGFR-2 inhibition. Among them, compound 6l exhibited the most potent inhibitory activities against VEGFR-2 (IC50=84 nM) and HDAC (IC50=2.
